The HG-140-15W semiconductor heater operates with a PTC thermistor. The heaters and heating fans prevent condensation of water vapor and maintain the proper operating temperature of the equipment.

For optimal airflow, vertical installation of the convection heaters at the bottom of the electrical panel is recommended. The device is intended exclusively for use inside closed electrical panels.

For safety reasons, a minimum distance of 50mm from cables and other devices is required. PTC thermistors are not intended for series connection.
